Sodium chloride and polydiallyl dimethyl ammonium chloride as an electroconductive additive

Abstract

Electroconductive paper useful typically in making copies by an electrostatic process may be made by incorporating therein NaCl and a polymer consisting of units derived from diallyl dimethyl ammonium chloride.

We claim: 
     
       1. Electroconductive paper including a layer of a coating composition containing sodium chloride and a water-soluble polymer consisting of units derived from diallyl dimethyl ammonium chloride, wherein the electroconductive paper contains about 0.1 to 3.0 pounds of the coating composition per 3,000 square feet of the paper and the molar ratio of the sodium chloride to the dialkyl dimethyl ammonium chloride ranges from 1:3 to 3:1. 
     
     
       2. The electroconductive paper of claim 1 wherein the coating composition contains equimolar amounts of the water-soluble polymer and the sodium chloride.
